Best Drive Disc sets for Dialyn

Dialyn's 4-piece set is King of the Summit. No other 4-piece set is recommended, so there is no substitute worth farming.

King of the Summit Best in slot

4-piece: When the equipper is a Stun character and uses an EX Special Attack or Chain Attack, increases CRIT DMG of all squad members by 15%, and when the equipper's CRIT Rate is more than or equal to 50%, further increases CRIT DMG by 15%, lasting 15s. Repeated triggers reset the duration. Passive effects of the same name do not stack

2-piece: Increases Daze of attacks by 6%. Drops from Words and Weapons.

2-piece options

For the 2-piece slot the bonus matters, not the set's name. Several sets share the same 2-piece bonus, so Dialyn can take it from whichever one you have spare pieces of:

CRIT Rate +8%: Woodpecker Electro
Energy Regen +20%: any of Swing Jazz or Moonlight Lullaby (they give the same bonus)

Dialyn main stats: Disk 4, 5 and 6

Disks 1 to 3 always roll HP, ATK and DEF as their main stat, so the choice is on 4, 5 and 6. A > means "better than"; = means the two are about as good.

Slot	Main stat, best first
Disk 4	CRIT Rate
Disk 5	ATK% > Physical DMG% = PEN Ratio
Disk 6	Energy Regen

Dialyn substat priority

Roll for CRIT Rate and CRIT DMG first. A disc showing neither of those is rarely worth levelling for Dialyn, whatever else it has.

CRIT Rate (until 100%)
CRIT DMG
ATK%
PEN
Flat ATK

Dialyn W-Engine and skill priority

Yesterday Calls S-rank, CRIT Rate sub-stat

Dialyn's signature is far ahead of everything else. It grants up to 27% Daze (not Impact), which scales cleanly with her, and a strong 30% CRIT DMG buff for every damage type, Lighter's signature buff without the element restriction. The real prize is 1.5 Energy Regen per second while off-field: more EX Specials means faster stuns and easier Positive Reviews.

Questions

What is the best Drive Disc set for Dialyn?

King of the Summit 4-piece. For the 2-piece, any set with CRIT Rate +8% or Energy Regen +20% works.

What main stats should Dialyn use on Disk 4, 5 and 6?

Disk 4: CRIT Rate. Disk 5: ATK% > Physical DMG% = PEN Ratio. Disk 6: Energy Regen. Disks 1 to 3 have fixed main stats (HP, ATK and DEF), so only their substats matter.

What substats does Dialyn need?

In priority order: CRIT Rate, CRIT DMG, ATK%, PEN, Flat ATK. The first two are what make a disc worth levelling for Dialyn; the rest are tiebreakers.

Where do I farm Dialyn's Drive Discs?

King of the Summit drops from the Words and Weapons Area Patrol stage, alongside Yunkui Tales. Each run at Lv.60 costs 60 Battery Charge and splits its S-rank discs between the two sets.
